Schwarzenegger says he’s feeling better, but he’s “not great yet.” He was seated at a chessboard, which he says he uses to freshen his mind and memory.

Schwarzenegger underwent a scheduled heart procedure on March 29. A pulmonic valve originally installed in 1997 for a congenital heart defect had to be replaced. Schwarzenegger’s spokesman, Daniel Ketchell said when the actor woke up from the procedure he said, “I’m back”.

The 70-year-old was released from Cedars-Sinai Medical Center in Los Angeles on April 6.
